Yes, ListCollectionView is written to retrieve all data before it executes the sort because the Sort object expects to sort everything at once. You could write your own ICollectionView and just not actually call Sort.sort()and do your own thing (look at the SortFields within the sort when refresh() is called and then adjust your custom IList as appropriate).

I wrote a custom class based on mx.collections.IList that retrieves the data in pages, handles caching and recycling of old items. Everything works fine so far. I've used a technique similar to Matt Chotin on his blog, but this works with Flex 2.0. Now I want to implement sorting on the Database. Flex 1.5 had a convenient mx.controls.listclasses.DataProvider class, which unfortunately isn't in Flex 2.0. What is the recommended way to implement remote sorting? Loading all data into memory and using ActionScript for sorting is not an option. I've tried wrapping a ListCollectionView around my custom IList with the aim of later providing a custom Sort class. This introduces it's own problems - the ListCollectionView wants to iterate over the entire list, which is a pain with large lists. Do I have to implement my own custom ICollectionView, IViewCursor, and extend Sort to achieve this? I can't see an easier way at the moment. Thanks for any advice, Dion. -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
